自振荡除霜设备以及其操作方法
摘要：
本公开涉及自振荡除霜设备以及其操作方法。一种热增加系统包括腔、安置在所述腔中的第一电极、安置在所述腔中的第二电极以及产生射频信号的自振荡器电路，所述射频信号被转换成通过所述第一电极和所述第二电极辐射到所述腔中的电磁能量。所述自振荡电路包括所述第一电极和所述第二电极。在一个实施例中，所述第一电极是电容器结构中的第一板，并且所述第二电极是所述电容器结构中的第二板。所述腔和容纳在所述腔内的负载作为所述电容器结构的电容器电介质操作。所述自振荡器电路的谐振频率至少部分地由所述电容器结构的电容值确定。
摘要（英）：

The disclosure relates to a self-oscillating defrosting apparatus and methods of their operation. A thermal increase system includes a cavity, a first electrode disposed in the cavity, a second electrode disposed in the cavity, and a self-oscillator circuit that produces a radio frequency signal that is converted into electromagnetic energy that is radiated into the cavity by the first and secondelectrodes. The self-oscillating circuit includes the first electrode and the second electrode. In an embodiment, the first electrode is a first plate in a capacitor structure and the second electrodeis a second plate in the capacitor structure. The cavity and a load contained within the cavity operates as a capacitor dielectric of the capacitor structure. A resonant frequency of the self-oscillator circuit is at least partially determined by a capacitance value of the capacitor structure.
